Smooth jazz cat Lee Ritenour returns to Temecula’s Thornton Winery June 10, with Dave Grusin and locally bred bassist Nathan East in tow. The participation of the 83-year-old Grusin is a rare occurrence on the lower left coast, although the ten-time Grammy winning composer has been recording with Ritenour since the mid-1970s, appearing on pivotal albums like 1977’s Captain Fingers. Ritenour’s guitar has been heard in over 3000 sessions, and his own songs have earned him well over two dozen contemporary chart hits. His most recent album, A Twist of Rit, spawned a top five hit on the U.S. Smooth Jazz chart, “A Little Bit of This and a Little Bit of That.” Star bassist Nathan East attended Crawford High before going on to play with Eric Clapton, George Harrison, Stevie Wonder, Michael Bublé, Quincy Jones, Kenny Loggins, Rod Stewart, Herbie Hancock, Wayne Shorter, Michael Jackson, B.B. King, Bob Dylan, Aretha Franklin, Joe Satriani, and many others (he also co-wrote the 1984 Phil Collins and Phillip Bailey hit “Easy Lover”).
